Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a bypass busbar prefabrication device and equipment. Background Technology

[0002] In photovoltaic (PV) module manufacturing, an insulating film tape needs to be placed between the busbars and the cell strings to prevent short circuits caused by contact between the busbars and the cells. There are two process paths for bonding the busbars and the film tape during PV module production: one is to pre-fix the film tape to the busbar, using an integrated busbar with pre-fixed film tape, and directly proceed to the cell string welding process; the other is to use busbars without pre-attached film tape, and during production, manually or mechanically position, attach, and fix the film tape to the busbar before proceeding with the cell string welding process.

[0003] Existing equipment for applying films to busbars typically involves first laying the insulating film flat on a heating table, then placing the cut busbar strip on the insulating film, and using the heat of the heating table to melt the hot melt adhesive on the insulating film, thus bonding the insulating film to the busbar strip.

[0004] The aforementioned equipment has difficulty controlling the temperature of the heating platform within a suitable range during the film application process. When the temperature of the heating platform is too low, the insulating film does not adhere firmly to the busbar and may even fail to adhere at all; while when the temperature of the heating platform is too high, it will damage the insulating film, resulting in poor film application of the busbar. Utility Model Content

[0005] The purpose of this application is to provide a bypass busbar prefabrication device and equipment to solve the technical problem of poor film application effect of the existing busbar strip.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A bypass busbar prefabrication device includes a base frame and an adsorption mechanism and a hot pressing mechanism disposed on the base frame, wherein:

[0008] The adsorption mechanism includes multiple suction cup assemblies arranged along a first direction, and the adsorption mechanism is used to pick up the busbar segment to be applied to the film.

[0009] The base frame is configured to move within space so that the manifold segment picked up by the adsorption mechanism is aligned and fitted with the flat-laid membrane tape;

[0010] The hot pressing mechanism includes multiple sets of heating components arranged along a first direction. The hot pressing mechanism is used to heat the busbar segments that are aligned and bonded to the membrane tape, so that the aligned and bonded busbar segments and the membrane tape are fixed by hot pressing.

[0011] This bypass busbar prefabrication device heats the busbar segments to fix them and the membrane tape together via thermo-pressing. This means the device does not directly heat the membrane tape (whose melting point is lower than the busbar), thus avoiding damage to the membrane tape due to overheating. Furthermore, the adsorption and thermo-pressing mechanisms are integrated on the base frame and can move with the base. During the film application process, there is no need to move the adsorption machine and thermo-pressing mechanism separately, simplifying the busbar application process and improving efficiency.

[0012] In some embodiments, the number of adsorption mechanisms is one, two, or more; when the number of adsorption mechanisms is two or more, each adsorption mechanism is arranged along the second direction.

[0013] The number of hot pressing mechanisms is one, two, or more; when the number of hot pressing mechanisms is two or more, each hot pressing mechanism is arranged along the second direction.

[0014] The first direction and the second direction are perpendicular to each other.

[0015] The number of adsorption and hot-pressing mechanisms can be one, two, or more. Correspondingly, the bypass busbar prefabrication device can simultaneously apply film to one, two, or more busbar segments. Setting the number of adsorption and hot-pressing mechanisms to at least two can improve film application efficiency and ensure compatibility with busbar segments with different process requirements.

[0016] In some embodiments, each heating assembly includes a thermo-pressure drive source and a heating element. The power output end of the thermo-pressure drive source is connected to the heating element. The thermo-pressure drive source is configured to drive the heating element to move along a third direction so that the heating element approaches or moves away from the busbar segment aligned and attached to the membrane strip. The first direction is perpendicular to the third direction.

[0017] During operation, the bypass busbar prefabrication device is oriented in a direction parallel to the thickness of the busbar segment. The heating element is suspended above the busbar segment on the adsorption mechanism. After the busbar segment on the adsorption mechanism is aligned and bonded to the membrane tape, the thermostatic drive source drives the heating element to approach the busbar segment so that the heating end of the heating element contacts the upper surface of the busbar segment. Then, the heating element heats the busbar segment to fix the busbar segment and the membrane tape through thermostatic pressing.

[0018] In some embodiments, the suction cup assembly includes a suction cup and an elastic element, wherein:

[0019] The suction cup is telescopically mounted on the base frame via an elastic element, and the suction cup has an initial position and a final position relative to the base frame.

[0020] When the suction cup is in the initial position, the suction end of the suction cup is higher than the heating end of the heating component in the third direction;

[0021] When the suction cup is in its final position, the suction end of the suction cup is flush with the heating end of the heating component in the third direction.

[0022] Among them, the first direction and the third direction are perpendicular to each other.

[0023] The elastic element serves two purposes: firstly, it enhances the adsorption effect of the adsorption mechanism. During the adsorption process, the elastic force of the elastic element ensures that the suction end of the suction cup is tightly attached to the surface of the manifold, thus firmly adsorbing the manifold onto the suction cup; secondly, it allows the heating end of the heating element to contact the manifold while the heating element remains stationary relative to the base frame.

[0024] In some embodiments, the adsorption mechanism further includes a plurality of mounting plates arranged along a first direction, each mounting plate being slidably disposed on a base frame along the first direction, and each mounting plate being provided with a plurality of suction cup assemblies and / or a plurality of heating assemblies;

[0025] The adsorption mechanism also includes a positioning component disposed between two adjacent mounting plates and configured to adjust the relative positions of the two adjacent mounting plates along a first direction.

[0026] The number of suction cup components and heating components on each mounting plate can be increased or decreased as needed. At the same time, the relative positions of each mounting plate along the first direction can also be adjusted as needed, so as to adapt to different types of battery strings.

[0027] In some embodiments, the bypass busbar prefabrication device further includes a bending mechanism and a clearance drive mechanism disposed on the base frame, wherein:

[0028] The bending mechanism is used to bend the busbar segments on the adsorption mechanism into a specified shape;

[0029] The power output end of the avoidance drive mechanism is connected to the bending mechanism via a transmission. The avoidance drive mechanism is configured to drive the bending mechanism to move along the width direction of the manifold segment to be absorbed, so that the position of the bending mechanism is offset from the positions of the adsorption mechanism and the hot pressing mechanism along the width direction of the manifold segment to be absorbed.

[0030] By incorporating a bending mechanism, the busbar segments can be bent into a specified shape, allowing the bypass busbar prefabrication device to sequentially perform adsorption, bending, and film application processes on the busbar segments. An obstacle avoidance drive mechanism moves the bending mechanism along the width of the busbar segment to be adsorbed. When the busbar is placed on the suction end of the suction cup assembly using a traction device, the bending mechanism can be driven away from the suction end of the suction cup assembly in advance. This ensures that the bending mechanism is offset from the adsorption and hot-pressing mechanisms along the width of the busbar segment to be adsorbed, preventing the bending mechanism from interfering with the extraction of the busbar.

[0031] In some embodiments, the bypass busbar prefabrication device further includes a transfer drive mechanism, the power output end of which is connected to the base frame in a transmission connection, and the transfer drive mechanism is configured to drive the base frame to move in space.

[0032] The base frame is driven to move along a set trajectory by the transfer drive mechanism, so that the adsorption mechanism can complete the picking and putting of the manifold segment.

[0033] A bypass busbar prefabrication device, comprising a support device, a busbar feeding device, a membrane belt feeding device, a traction device, a busbar cutting device, a membrane belt cutting device, and any one of the above-mentioned bypass busbar prefabrication devices, wherein:

[0034] The support device is used to support the membrane strip;

[0035] The busbar feeding device is used to supply busbars;

[0036] The membrane tape feeding device is used to supply membrane tape;

[0037] The traction device is used to pull the manifold from the manifold feeding device to a specified length, and / or to pull the membrane belt from the membrane belt feeding device onto the support device;

[0038] The busbar cutting device is used to cut the busbars drawn from the busbar feeding device to obtain busbar segments;

[0039] The film tape cutting device is used to cut the film tape led out from the film tape feeding device to obtain film tape segments.

[0040] This bypass busbar prefabrication equipment can automatically complete the cutting and preparation processes of busbar segments and membrane tape segments, as well as the membrane application process. Its high degree of automation reduces manual labor. The equipment heats the busbar segments to fix them to the membrane tape via thermo-pressing; that is, it does not directly heat the membrane tape, thus avoiding damage caused by overheating.

[0041] In some embodiments, the busbar feeding device includes a busbar feeding frame and a plurality of busbar roll feeding mechanisms disposed on the busbar feeding frame, wherein the busbar lead-out positions of the plurality of busbar roll feeding mechanisms are arranged along a second direction, and the busbar feeding frame is configured to be movable relative to the traction device along the second direction.

[0042] And / or, the film tape feeding device includes a film tape feeding frame and a plurality of film tape roll feeding mechanisms disposed on the film tape feeding frame, the film tape lead-out positions of the plurality of film tape roll feeding mechanisms being arranged along a second direction, and the film tape feeding frame being configured to be movable relative to the traction device along the second direction.

[0043] By setting up multiple busbar roll feeding mechanisms, once the current busbar roll feeding mechanism is exhausted, the busbar feeder can be moved along the second direction to switch to another busbar roll feeding mechanism, thus enabling rapid material replenishment and improving the processing efficiency of the equipment. Similarly, by setting up multiple film roll feeding mechanisms, once the current film roll feeding mechanism is exhausted, the film roll feeder can be moved along the second direction to switch to another film roll feeding mechanism.

[0044] In some embodiments, the bypass busbar prefabrication equipment further includes a correction device, which comprises a pressing mechanism and a correction drive mechanism, wherein:

[0045] The briquetting mechanism includes two briquetting blocks configured to approach each other to clamp the manifold from the manifold feeder or the membrane belt from the membrane belt feeder.

[0046] The power output end of the correction drive mechanism is connected to the briquetting mechanism. The correction drive mechanism is configured to drive the briquetting mechanism to move along the width direction of the busbar leading from the busbar feeding device or the width direction of the membrane belt leading from the membrane belt feeding device.

[0047] The correction device can be used to correct the deviation of busbars drawn from the busbar feeding device, or to correct the deviation of membrane belts drawn from the membrane belt feeding device. Taking the correction device for busbars drawn from the busbar feeding device as an example, the working principle of the correction device is as follows: when the busbar deviates from the set trajectory in the width direction, the two pressure blocks are controlled to clamp the busbar. Then, the correction drive mechanism drives the two pressure blocks to move along the width direction of the busbar. The two pressure blocks then drive the busbar clamped between them to move synchronously, thereby adjusting the busbar to the set trajectory.

[0048] In some embodiments, the busbar cutting device is slidably disposed on the support device along a first direction;

[0049] And / or, the busbar cutting device includes a busbar clamping mechanism for clamping the busbar;

[0050] And / or, the busbar cutting device includes a busbar positioning structure for detecting the position of the busbar;

[0051] And / or, the busbar cutting device includes a busbar cutting mechanism for cutting the busbar;

[0052] The first direction is parallel to the length direction of the busbar extending from the busbar feeding device.

[0053] By sliding the busbar cutting device along a first direction onto the support device, the cutting position of the busbar can be adjusted to accommodate different battery string designs. The busbar clamping mechanism clamps the busbar before cutting to prevent displacement. The busbar positioning structure detects the presence of a busbar below it, determining whether to proceed to the next step. After the busbar is pulled to the specified length, the busbar cutting mechanism cuts it to obtain a busbar segment of the specified length.

[0054] In some embodiments, the film strip cutting device is slidably disposed on the support device along a first direction;

[0055] And / or, the film tape cutting device includes a film tape clamping mechanism for clamping the film tape;

[0056] And / or, the film tape cutting device includes a film tape positioning structure for detecting the position of the film tape;

[0057] And / or, the film tape cutting device includes a film tape cutting mechanism for cutting the film tape;

[0058] The first direction is parallel to the length direction of the film belt drawn from the film belt feeding device.

[0059] By sliding the membrane tape cutting device along the first direction onto the support device, the cutting position of the membrane tape can be adjusted to accommodate different types of battery strings. The membrane tape clamping mechanism clamps the membrane tape before cutting to prevent displacement. The membrane tape positioning structure detects the presence of membrane tape underneath it, determining whether to proceed to the next step. After the membrane tape is pulled to the specified length, the membrane tape cutting mechanism cuts the membrane tape to obtain a membrane tape segment of the specified length.

[0060] In some embodiments, the busbar feeding device and the membrane belt feeding device are respectively disposed at both ends of the support device along the length direction;

[0061] The traction device includes a traction clamping mechanism and a traction drive mechanism, wherein:

[0062] The traction clamping mechanism includes two pairs of traction jaws, one pair of which is used to clamp the busbars drawn from the busbar feeding device, and the other pair of traction jaws is used to clamp the film belt drawn from the film belt feeding device.

[0063] The power output end of the traction drive mechanism is connected to the traction clamping mechanism via a transmission connection. The traction drive mechanism is configured to drive the traction clamping mechanism to move between the busbar feeding device and the membrane belt feeding device.

[0064] Since the matching set of busbar feeding device and membrane belt feeding device are respectively set at both ends of the support device along the length direction, the two can share a traction device. This not only saves the manufacturing cost of a traction device and makes the overall structure of the equipment more compact, but also ensures that a set of pulled busbars and membrane belts are in the same position. Thus, only a simple lifting and lowering movement of the cut busbar segments is needed to align and fit a set of busbar segments and membrane belts.

[0065] In some embodiments, the traction clamping mechanism further includes a traction gripper drive source, which has two power output ends that are respectively connected to two pairs of traction grippers in a transmission.

[0066] Alternatively, the traction clamping mechanism may also include a traction gripper drive source, the power output end of which is connected to two pairs of traction grippers simultaneously through a transmission structure.

[0067] Alternatively, the traction clamping mechanism includes two traction jaw drive sources, and the power output ends of the two traction jaw drive sources are respectively connected to two pairs of traction jaws for transmission.

[0068] The power output end of the traction gripper drive source can be directly connected to the two traction grippers, or it can be connected to the two pairs of traction grippers through a transmission structure. Both of these connection methods can enable the two pairs of traction grippers to open or close by driving the traction gripper drive source.

[0069] In some embodiments, the number of busbar feeding devices is two, namely a first busbar feeding device and a second busbar feeding device, and the number of membrane belt feeding devices is two, namely a first membrane belt feeding device and a second membrane belt feeding device. The first busbar feeding device and the first membrane belt feeding device are configured in pairs, and the second busbar feeding device and the second membrane belt feeding device are configured in pairs.

[0070] The first busbar feeding device and the second membrane belt feeding device are both located at one end of the support device along the length direction, and the second busbar feeding device and the first membrane belt feeding device are both located at the other end of the support device along the length direction. The first busbar feeding device, the first membrane belt feeding device, the second busbar feeding device, and the second membrane belt feeding device are arranged diagonally and cross each other.

[0071] By arranging the first busbar feeding device, the first membrane belt feeding device, the second busbar feeding device, and the second membrane belt feeding device at an oblique angle, the feeding of the two sets of busbars and membrane belts can be completed simultaneously without interference between the feeding devices, thereby improving processing efficiency.

[0097] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0099] It should be noted that, in the description of this application, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0100] Existing equipment for applying films to busbars typically places the insulating film on a heating platform, then places the busbar on top of the film. The heat from the platform melts the hot melt adhesive on the insulating film, bonding it to the busbar. However, during the heating process, this method can easily lead to overheating and damage to the insulating film in order to ensure a strong bond, resulting in poor film application.

[0101] Based on this, one embodiment of this application provides a bypass busbar prefabrication device 1, referring to... Figure 1 The bypass busbar prefabrication device 1 includes a base frame 11 and an adsorption mechanism 12 and a hot pressing mechanism 13 disposed on the base frame 11, wherein:

[0102] The adsorption mechanism 12 includes a plurality of suction cup assemblies 121 arranged along a first direction. The adsorption mechanism 12 is used to pick up the manifold segment 100 to be applied to the film.

[0103] The base frame 11 is configured to move in space so that the manifold segment 100 picked up by the adsorption mechanism 12 is aligned and adhered to the flat-laid membrane tape;

[0104] The hot pressing mechanism 13 includes multiple sets of heating components 131 arranged along a first direction. The hot pressing mechanism 13 is used to heat the busbar segment 100 that is aligned and bonded to the membrane tape, so that the aligned and bonded busbar segment 100 and the membrane tape are fixed by hot pressing.

[0105] During operation, the bypass busbar prefabrication device 1 operates with its first direction (i.e., the arrangement direction of the suction cup assembly 121 and the heating assembly 131) parallel to the length direction of the busbar segment 100. Thus, multiple sets of suction cup assemblies 121 pick up the busbar segment 100 at multiple positions along the length direction of the busbar segment 100, and multiple sets of heating assemblies 131 heat the busbar segment 100 at multiple positions along the length direction of the busbar segment 100. The device operates as follows: first, the prepared membrane strip is laid flat; then, the base frame 11 is moved, causing the adsorption mechanism 12 and the hot-pressing mechanism 13 on the base frame 11 to move, aligning and bonding the busbar segment 100 to be bonded with the flat-laid membrane strip on the adsorption mechanism 12; after the busbar segment 100 and the membrane strip are aligned and bonded, the hot-pressing mechanism 13 heats the busbar segment 100, thereby fixing the aligned and bonded busbar segment 100 and the membrane strip through hot pressing.

[0106] Compared to existing equipment for applying films to busbars, the bypass busbar prefabrication device 1 provided in this application heats the busbar segment 100 to fix the busbar segment 100 and the film strip through hot pressing. That is, this device does not directly heat the film strip (the melting point of the film strip is lower than that of the busbar), thus avoiding the problem of damaging the film strip due to overheating. Furthermore, the adsorption mechanism 12 and the hot pressing mechanism 13 are integrated on the base frame 11 and can move with the base frame 11. During the film application process, there is no need to move the adsorption mechanism 12 and the hot pressing mechanism 13 separately, thereby simplifying the film application process of the busbar segment 100 and improving the film application efficiency.

[0107] Optionally, the number of adsorption mechanisms 12 is one, two or more; when the number of adsorption mechanisms 12 is two or more, each adsorption mechanism 12 is arranged along the second direction;

[0108] The number of hot pressing mechanisms 13 is one, two or more; when the number of hot pressing mechanisms 13 is two or more, each hot pressing mechanism 13 is arranged along the second direction;

[0109] The first direction and the second direction are perpendicular to each other.

[0110] During operation, the bypass busbar prefabrication device 1 operates in a second direction parallel to the width direction of the busbar segment 100. The number of adsorption mechanisms 12 and hot-pressing mechanisms 13 can be one, two, or more. Correspondingly, the bypass busbar prefabrication device 1 can simultaneously apply film to one, two, or more busbar segments 100. Setting the number of adsorption mechanisms 12 and hot-pressing mechanisms 13 to at least two can improve film application efficiency and ensure compatibility with busbar segments 100 requiring different processes.

[0111] Figure 1 In the illustrated embodiment, there are two adsorption mechanisms 12 and two hot-pressing mechanisms 13, and the adsorption mechanisms 12 and hot-pressing mechanisms 13 are arranged in a one-to-one correspondence. In a corresponding set of adsorption mechanisms 12 and hot-pressing mechanisms 13, the suction cup assembly 121 and the heating assembly 131 are arranged side by side along the first direction. The suction cup assembly 121 and the heating assembly 131 can be arranged alternately, or one or more sets of heating assemblies 131 can be arranged between every two adjacent sets of suction cup assemblies 121. The specific arrangement can be adjusted according to the actual situation.

[0112] Reference Figure 2 In some embodiments, the adsorption mechanism 12 further includes a plurality of mounting plates 122 arranged along a first direction, each mounting plate 122 being slidably disposed on the base frame 11 along the first direction, and each mounting plate 122 being provided with a plurality of suction cup assemblies 121 and / or a plurality of heating assemblies 131.

[0113] The adsorption mechanism 12 also includes an adjustment component 123, which is disposed between two adjacent mounting plates 122 and is configured to adjust the relative position of the two adjacent mounting plates 122 along a first direction.

[0114] In the above structure, the number of suction cup assemblies 121 and heating assemblies 131 on each mounting plate 122 can be increased or decreased as needed. At the same time, the relative positions of each mounting plate 122 along the first direction can also be adjusted as needed, so as to adapt to different types of battery strings.

[0115] Specifically, there are at least two mounting plates 122, and correspondingly, there is at least one set of adjusting components 123. Taking one set of adjusting components 123 and two adjacent mounting plates 122 as an example, the adjusting component 123 includes a connecting rod 1232 and two connecting blocks 1231. The connecting rod 1232 has an adjusting elongated hole 1233, the length of which is parallel to the first direction. Screws or other fasteners pass through the adjusting elongated hole 1233 and are screwed to the connecting blocks 1231. The two connecting blocks 1231 correspond one-to-one with the two mounting plates 122, and a corresponding set of connecting blocks 1231 and mounting plates 122 are fixedly connected by screws or other fasteners. In this structure, the adjusting elongated hole 1233 provides an adjustment range for the screws within it, allowing the relative position of the two connecting blocks 1231 to be adjusted, thereby adjusting the relative position of the two mounting plates 122, ultimately achieving the purpose of adjusting the relative position of each mounting plate 122 along the first direction.

[0116] Reference Figure 3 In some embodiments, the adsorption mechanism 12 further includes a guide assembly 124, which includes a guide rail and a slider. The guide rail extends along a first direction and is disposed on the base frame 11. The slider is slidably disposed on the guide rail and connected to the mounting plate 122. Specifically, the mounting plate 122 has a front and a back side disposed opposite to each other. The front side of the mounting plate 122 is equipped with a suction cup assembly 121 and / or a heating assembly 131. There are multiple sliders, and at least one slider is fixedly disposed on the back side of each mounting plate 122 (the number can be adjusted according to the length of the mounting plate 122). The guide assembly 124 can limit the movement trajectory of each mounting plate 122, ensuring that each mounting plate 122 moves along the first direction.

[0117] Continue to refer to Figure 2 In some embodiments, each heating assembly 131 includes a thermo-pressure driving source 1311 and a heating element 1312. The power output end of the thermo-pressure driving source 1311 is connected to the heating element 1312. The thermo-pressure driving source 1311 is configured to drive the heating element 1312 to move along a third direction so that the heating element 1312 approaches or moves away from the busbar segment 100 that is aligned and attached to the membrane tape. The first direction, the second direction, and the third direction are perpendicular to each other.

[0118] During operation, the bypass busbar prefabrication device 1 is oriented in a direction parallel to the thickness of the busbar segment 100. The heating element 1312 is suspended above the busbar segment 100 on the adsorption mechanism 12. After the busbar segment 100 on the adsorption mechanism 12 is aligned and attached to the membrane tape, the hot-pressing drive source 1311 drives the heating element 1312 to approach the busbar segment 100 so that the heating end of the heating element 1312 contacts the upper surface of the busbar segment 100. Then, the heating element 1312 heats the busbar segment 100 to fix the busbar segment 100 and the membrane tape by hot pressing.

[0119] Optionally, the thermostatic driving source 1311 is a piston cylinder (which can be a pneumatic cylinder or a hydraulic cylinder), with the cylinder body mounted on the base frame 11 (specifically, on the mounting plate 122), and the heating element 1312 mounted on the end of the extension rod of the piston cylinder. Alternatively, the thermostatic driving source 1311 can also be a motor, which can be connected to the heating element 1312 via a transmission structure such as a lead screw and nut.

[0120] Optionally, the heating element 1312 is a hot-pressing head or a hot-pressing plate. The heating element 1312 only needs to be able to generate heat to heat the busbar segment 100, and it can be columnar, plate-shaped, block-shaped or other irregular shapes. Figure 2 In the embodiment shown, the heating element 1312 is a columnar heating head that can heat the busbar segment 100 by spot heating. This spot heating method can prevent the heating end of the heating element 1312 from contacting areas outside the busbar segment 100.

[0121] Reference Figure 4 and Figure 5 In some embodiments, the suction cup assembly 121 includes a suction cup 1211 and an elastic element 1212, wherein:

[0122] The suction cup 1211 is telescopically mounted on the base frame 11 along a third direction via an elastic member 1212, and the suction cup 1211 has an initial position relative to the base frame 11 and a final position relative to the base frame 11.

[0123] When the suction cup 1211 is in the initial position, the suction end of the suction cup 1211 is higher than the heating end of the heating component 131 (specifically the heating end of the heating element 1312) in the third direction.

[0124] When the suction cup 1211 is in its final position, the suction end of the suction cup 1211 is flush with the heating end of the heating component 131 in the third direction.

[0125] Among them, the first direction and the third direction are perpendicular to each other.

[0126] The elastic element 1212 serves two purposes. First, it enhances the adsorption effect of the adsorption mechanism 12. During the adsorption process of the adsorption mechanism 12 adsorbing the manifold segment 100, the elastic force of the elastic element 1212 ensures that the suction end of the suction cup 1211 is tightly attached to the surface of the manifold segment 100, thereby firmly adsorbing the manifold segment 100 onto the suction cup 1211. Second, it allows the heating end of the heating element 1312 to contact the manifold segment 100 while the heating element 1312 remains stationary relative to the base frame 11. (Refer to...) Figure 5 When hot pressing the busbar segment 100 and the membrane tape, the base frame 11 can be controlled to move in the direction of approaching the busbar segment 100. At this time, the heating element 1312 moves synchronously with the base frame 11 to approach the busbar segment 100, while the suction cup 1211 is fixed relative to the busbar segment 100 under the action of the elastic element 1212, so that the heating end of the heating element 1312 can smoothly contact the busbar segment 100.

[0127] Optionally, the elastic element 1212 can be a compression spring or a tension spring, and the elastic element 1212 can elastically deform in a third direction.

[0128] Figure 4 In the illustrated embodiment, the elastic element 1212 is a compression spring; the suction cup assembly 121 further includes a guide shell 1213 disposed on the base frame 11 (specifically, the mounting plate 122), the guide shell 1213 having a hollow structure, the suction cup 1211 slidingly passing through the guide shell 1213 in a third direction, and the suction end of the suction cup 1211 extending out from inside the guide shell 1213; the elastic element 1212 is fitted onto the suction cup 1211 and connected between the suction cup 1211 and the guide shell 1213. Further, a positioning ring platform is provided on the inner wall surface of the guide shell 1213, and a positioning shoulder is provided on the circumferential surface of the suction cup 1211, the positioning ring platform and the positioning shoulder cooperating to limit the initial position of the suction cup 1211; the guide shell 1213 includes a detachably connected guide shell body and a cover plate, the elastic element 1212 is located inside the guide shell 1213 and its two ends abut against the positioning shoulder and the cover plate on the suction cup 1211 respectively.

[0129] It should be noted that although the elastic element 1212 allows the heating end of the heating element 1312 to contact the busbar segment 100 while the heating element 1312 remains stationary relative to the base frame 11, the simultaneous installation of the elastic element 1212 and the thermostatic driving source 1311 does not conflict. In the embodiment where both the elastic element 1212 and the thermostatic driving source 1311 are provided, when heating the busbar segment 100, the base frame 11 and the suction cup 1211 remain stationary, and the thermostatic driving source 1311 drives the heating element 1312 to move relative to the base frame 11 in a direction close to the busbar segment 100; in this embodiment, the elastic element 1212 only serves to enhance the adsorption effect of the adsorption mechanism 12.

[0130] Reference Figure 1 and Figure 6 In some embodiments, the bypass busbar prefabrication device 1 further includes a bending mechanism 15 and a clearance drive mechanism 16 disposed on the base frame 11, wherein:

[0131] Bending mechanism 15 is used to bend the busbar segment 100 on adsorption mechanism 12 into a specified shape;

[0132] The power output end of the avoidance drive mechanism 16 is connected to the bending mechanism 15. The avoidance drive mechanism 16 is configured to drive the bending mechanism 15 to move along the width direction of the manifold segment 100 to be absorbed, so that the position of the bending mechanism 15 is offset from the positions of the adsorption mechanism 12 and the hot pressing mechanism 13 along the width direction of the manifold segment 100 to be absorbed.

[0133] By setting the bending mechanism 15, the busbar segment 100 can be bent into a specified shape, so that the bypass busbar prefabrication device 1 can sequentially perform the adsorption process, bending process, and film application process on the busbar segment 100. By setting the avoidance drive mechanism 16 to drive the bending mechanism 15 to move along the width direction of the busbar segment 100 to be picked up, when the busbar is placed on the suction end of the suction cup assembly 121 by the traction device, the bending mechanism 15 can be driven away from the suction end of the suction cup assembly 121 in advance, so that the bending mechanism 15 is staggered from the adsorption mechanism 12 and the hot pressing mechanism 13 along the width direction of the busbar segment 100 to be picked up, so as to prevent the bending mechanism 15 from interfering with the pulling out of the busbar.

[0134] Reference Figure 7 The obstacle avoidance drive mechanism 16 includes an obstacle avoidance slide 161 and an obstacle avoidance drive source 162. The obstacle avoidance slide 161 is slidably mounted on the base frame 11 along a second direction, and the bending mechanism 15 is mounted on the obstacle avoidance slide 161. The obstacle avoidance drive source 162 is mounted on the base frame 11, and its power output end is connected to the obstacle avoidance slide 161. The obstacle avoidance drive source 162 can be any of a motor, electric cylinder, or piston cylinder. Its power output end can be directly connected to the bending mechanism 15, or it can be connected to the bending mechanism 15 using a lead screw and nut, gear and rack, or other transmission structures. This application does not impose specific limitations. Furthermore, to enable the obstacle avoidance slide 161 to slide along a set trajectory, a guide rail slider assembly can be provided between the obstacle avoidance slide 161 and the base frame 11.

[0135] Continue to refer to Figure 6In some embodiments, the bypass busbar prefabrication device 1 further includes a transfer drive mechanism 14. The power output end of the transfer drive mechanism 14 is connected to the base frame 11 via a transmission connection. The transfer drive mechanism 14 is configured to drive the base frame 11 to move within space. The transfer drive mechanism 14 can be configured to drive the base frame 11 to move relative to the entire device along one or more directions of a first direction, a second direction, and a third direction. It can also be configured to drive the base frame 11 to rotate relative to the entire device. By driving the base frame 11 to move along a set trajectory through the transfer drive mechanism 14, the adsorption mechanism 12 can complete the picking and placing action of the busbar segment 100.

[0136] The transfer drive mechanism 14 may include one or more transfer drive sources, which can be any of the following: motor, electric cylinder, or piston cylinder. Its power output end can be directly connected to the base frame 11 for transmission, or it can be connected to the base frame 11 for transmission using a lead screw and nut, gear and rack, or other transmission structures. In addition, the transfer drive mechanism 14 can also be a six-axis robot.

[0137] Reference Figure 8 Another embodiment of this application provides a bypass busbar prefabrication device, which includes a support device 2, a busbar feeding device 3, a membrane belt feeding device 4, a traction device 5, a busbar cutting device 6, a membrane belt cutting device 7, and the bypass busbar prefabrication device 1 described in any of the above embodiments, wherein:

[0138] Support device 2 is used to support the membrane strip;

[0139] Busbar feeding device 3 is used to supply busbars;

[0140] The membrane tape feeding device 4 is used to supply membrane tape;

[0141] The traction device 5 is used to pull the busbar from the busbar feeding device 3 to a specified length, and / or to pull the membrane belt from the membrane belt feeding device 4 onto the support device 2;

[0142] The busbar cutting device 6 is used to cut the busbars led out from the busbar feeding device 3 to obtain busbar segments 100;

[0143] The film belt cutting device 7 is used to cut the film belt led out from the film belt feeding device 4 to obtain film belt segments.

[0144] One of the feasible working processes for the aforementioned bypass busbar prefabrication equipment is as follows:

[0145] First, the traction device 5 pulls the busbar from the busbar feeding device 3 onto the support device 2 and is located below the suction end of the adsorption mechanism 12. When the busbar is pulled to a specified length, the busbar is cut by the busbar cutting device 6 to obtain a busbar segment 100 of a specified length. The transfer drive mechanism 14 drives the base frame 11 and the adsorption mechanism 12 and the hot pressing mechanism 13 on the base frame 11 to move synchronously, so that the adsorption mechanism 12 picks up the busbar segment 100.

[0146] Next, the traction device 5 pulls the film belt from the film belt feeding device 4 onto the support device 2. When the film belt is pulled to a specified length, the film belt cutting device 7 cuts the film belt to obtain a film belt segment of the specified length.

[0147] Subsequently, the transfer drive mechanism 14 drives the base frame 11 and the adsorption mechanism 12 and the hot pressing mechanism 13 on the base frame 11 to move synchronously, so that the manifold segment 100 on the adsorption mechanism 12 is aligned and attached to the membrane strip on the support device 2; after the manifold segment 100 is aligned and attached to the membrane strip, the hot pressing mechanism 13 heats the manifold segment 100 so that the manifold segment 100 and the membrane strip are fixed by hot pressing.

[0148] The bypass busbar prefabrication equipment provided in this application can automatically complete the cutting and preparation processes of busbar segments and membrane tape segments, as well as the membrane application process. It has a high degree of automation, reducing manual labor. The equipment heats the busbar segment 100 to fix it and the membrane tape through hot pressing; that is, the equipment does not directly heat the membrane tape, thus avoiding damage to the membrane tape due to overheating.

[0149] Reference Figure 8 and Figure 9 In some embodiments, the busbar feeding device 3 and the membrane belt feeding device 4 are respectively disposed at both ends of the support device 2 along the length direction;

[0150] The traction device 5 includes a traction clamping mechanism 51 and a traction drive mechanism 52, wherein:

[0151] The traction clamping mechanism 51 includes two pairs of traction jaws 511, one pair of traction jaws 511 for clamping the busbars drawn from the busbar feeding device 3, and the other pair of traction jaws 511 for clamping the film belt drawn from the film belt feeding device 4.

[0152] The power output end of the traction drive mechanism 52 is connected to the traction clamping mechanism 51 via a transmission. The traction drive mechanism 52 is configured to drive the traction clamping mechanism 51 to move between the busbar feeding device 3 and the membrane belt feeding device 4.

[0153] Optionally, the number of busbar feeding device 3, membrane belt feeding device 4 and traction device 5 can be one, two or more, and the busbar feeding device 3, membrane belt feeding device 4 and traction device 5 are matched and configured one-to-one. A set of matching busbar feeding device 3, membrane belt feeding device 4 and traction device 5 work together to complete the traction work of a set of busbars and membrane belts.

[0154] In this embodiment, the length direction of the supporting device 2, the length direction of the busbar leading from the busbar feeding device 3, and the length direction of the membrane belt leading from the membrane belt feeding device 4 are all parallel to the first direction. The width direction of the supporting device 2, the width direction of the busbar leading from the busbar feeding device 3, and the width direction of the membrane belt leading from the membrane belt feeding device 4 are all parallel to the second direction. In this way, the membrane belt pulled out from the membrane belt feeding device 4 can be directly laid flat on the supporting device 2. The length direction of the cut busbar and the membrane belt is parallel. The busbar segment 100 can be placed on the membrane belt simply by moving the busbar segment 100 in the third direction.

[0155] Since the matching set of busbar feeding device 3 and membrane belt feeding device 4 are respectively set at both ends of the support device along the length direction, the two can share a traction device 5. This not only saves the manufacturing cost of a traction device 5 and makes the overall structure of the equipment more compact, but also ensures that a set of pulled busbars and membrane belts are in the same position. Thus, only a simple lifting and lowering movement of the cut busbar segments 100 is needed to align and fit a set of busbar segments 100 and membrane belts.

[0156] Optionally, the traction clamping mechanism 51 further includes a traction gripper drive source 512, which has two power output ends that are respectively connected to the two pairs of traction grippers 511.

[0157] Alternatively, the traction clamping mechanism 51 may also include a traction gripper drive source 512, the power output end of which is connected to two pairs of traction grippers 511 simultaneously through a transmission structure.

[0158] Alternatively, the traction clamping mechanism 51 includes two traction jaw drive sources 512, and the power output ends of the two traction jaw drive sources 512 are respectively connected to two pairs of traction jaws 511 for transmission.

[0159] exist Figure 9In the illustrated embodiment, the traction clamping mechanism 51 further includes a traction jaw drive source 512 that simultaneously drives two pairs of traction jaws 511 to open or close. Specifically, the traction clamping mechanism 51 also includes a traction slide seat slidably disposed on the support device 2 along a first direction. Each pair of traction jaws 511 consists of a fixed jaw and a movable jaw hinged together. The traction jaw drive source 512 is a bidirectional cylinder. The cylinder body of the traction jaw drive source 512 and each fixed jaw are fixedly mounted on the traction slide seat. The two telescopic ends of the traction jaw drive source 512 are respectively hinged to the two movable jaws. When the two telescopic ends of the traction jaw drive source 512 extend or retract simultaneously, the movable jaw in each pair of traction jaws 511 rotates relative to the fixed jaw, thereby realizing the opening or closing of each pair of traction jaws 511.

[0160] In some other embodiments, the power output end of the traction gripper drive source 512 is simultaneously connected to two pairs of traction grippers 511 via a transmission structure. In other still embodiments, the traction clamping mechanism 51 may further include two traction gripper drive sources 512 that respectively drive the two pairs of traction grippers 511 to open or close. The traction gripper drive source 512 may be a cylinder, a hydraulic cylinder, or a motor, and there is no limitation herein.

[0161] Reference Figure 10 Optionally, the busbar cutting device 6 is slidably disposed on the support device 2 along the first direction;

[0162] And / or, the busbar cutting device 6 includes a busbar clamping mechanism 61 for clamping the busbar;

[0163] And / or, the busbar cutting device 6 includes a busbar positioning structure 62 for detecting the position of the busbar;

[0164] And / or, the busbar cutting device 6 includes a busbar cutting mechanism 63 for cutting the busbar;

[0165] The first direction is parallel to the length direction of the busbar extending from the busbar feeding device 3.

[0166] By sliding the busbar cutting device 6 along the first direction on the support device 2, the cutting position of the busbar can be adjusted to adapt to different types of battery strings. The busbar cutting device 6 can be adjusted manually or automatically. When the busbar cutting device 6 is adjusted automatically, it also includes a busbar cutting base that provides support and an adjustment drive source for driving the busbar cutting base to move relative to the support device 2 along the first direction. The adjustment drive source can be any one of a motor, electric cylinder, or piston cylinder, and its power output end can be connected to the busbar cutting base via a transmission structure such as a lead screw and nut or a gear and rack.

[0167] Furthermore, the busbar clamping mechanism 61 includes a support platform 611, a pressure head 612, and a pressure head drive source 613. The support platform 611 is fixedly mounted on the busbar cutting base, and the pressure head drive source 613 is mounted on the busbar cutting base and configured to drive the pressure head 612 to move in a direction approaching or away from the support platform 611 to clamp or release the busbar. The busbar clamping mechanism 61 can clamp the busbar before cutting to prevent the busbar from shifting.

[0168] Furthermore, the busbar positioning structure 62 can be a through-beam or reflective photoelectric sensor. The busbar positioning structure 62 can detect whether there is a busbar below it, and determine whether to proceed to the next step based on the busbar positioning structure 62.

[0169] Furthermore, the busbar cutting mechanism 63 includes a cutter 631 and a cutter drive source 632. The pressure head drive source 613 is disposed on the busbar cutting base and is configured to drive the cutter 631 to move in a direction approaching or away from the outgoing busbar to cut the busbar.

[0170] Reference Figure 11 Optionally, the film strip cutting device 7 is slidably disposed on the support device 2 along the first direction;

[0171] And / or, the film tape cutting device 7 includes a film tape clamping mechanism 71 for clamping the film tape;

[0172] And / or, the film tape cutting device 7 includes a film tape positioning structure 72 for detecting the position of the film tape;

[0173] And / or, the film tape cutting device 7 includes a film tape cutting mechanism 73 for cutting the film tape;

[0174] The first direction is parallel to the length direction of the film belt led out from the film belt feeding device 4.

[0175] By sliding the membrane tape cutting device 7 along the first direction on the support device 2, the cutting position of the busbar can be adjusted to adapt to different types of battery strings. The membrane tape cutting device 7 can be adjusted manually or automatically. When the membrane tape cutting device 7 is adjusted automatically, it also includes a membrane tape cutting base that provides support and an adjustment drive source for driving the membrane tape cutting base to move relative to the support device 2 along the first direction.

[0176] Furthermore, the film tape clamping mechanism 71 includes two clamping blocks 711 and a clamping block drive source 712, which is configured to drive the two clamping blocks 711 to approach or move away from each other to clamp or release the film tape. The film tape clamping mechanism 71 can clamp the film tape before it is cut to prevent the film tape from shifting.

[0177] Furthermore, the membrane strip positioning structure 72 can be a through-beam or reflective photoelectric sensor. The membrane strip positioning structure 72 can detect whether there is a membrane strip below it, and determine whether to proceed to the next step based on the membrane strip positioning structure 72.

[0178] Furthermore, the membrane tape cutting mechanism 73 includes scissors 731 and scissor drive source 732, which is disposed on the busbar cutting base and configured to drive the scissors 731 to perform a cutting action to cut the membrane tape.

[0179] Reference Figure 12 In some embodiments, the bypass busbar prefabrication equipment further includes a correction device 8, which includes a pressing mechanism 81 and a correction drive mechanism 82, wherein:

[0180] The briquetting mechanism 81 includes two briquetting blocks 811, which are configured to approach each other to clamp the manifold from the manifold feeder 3 or the membrane belt from the membrane belt feeder 4.

[0181] The power output end of the correction drive mechanism 82 is connected to the pressing mechanism 81 via a transmission. The correction drive mechanism 82 is configured to drive the pressing mechanism 81 to move along the width direction of the busbar leading from the busbar feeding device 3 or the width direction of the membrane belt leading from the membrane belt feeding device 4.

[0182] The correction device 8 can be used to correct the deviation of the busbars drawn from the busbar feeding device 3, and it can also be used to correct the deviation of the membrane belt drawn from the membrane belt feeding device 4. In order to correct the deviation of both the busbars and the membrane belt, a correction device 8 is provided on the front side of the busbar drawing position of each busbar feeding device 3 (i.e., the side where the busbar is pulled out) and on the front side of the membrane belt drawing position of each membrane belt feeding device 4 (i.e., the side where the membrane belt is pulled out).

[0183] To achieve the movement of the two pressure blocks 811 approaching or moving away from each other, the pressure block mechanism 81 also includes a pressure block drive source 812 for driving the two pressure blocks 811 to approach or move away from each other. Taking the correction device 8 for correcting the busbars led out from the busbar feeding device 3 as an example, the working principle of the correction device 8 is as follows: when the busbar deviates from the set trajectory in the width direction, the pressure block drive source 812 drives the two pressure blocks 811 to clamp the busbar. Then, the correction drive mechanism 82 drives the two pressure blocks 811 to move along the width direction of the busbar. The two pressure blocks 811 then drive the busbar clamped between them to move synchronously, thereby adjusting the busbar to the set trajectory.

[0184] Continue to refer to Figure 8In some embodiments, there are two busbar feeding devices 3, which are respectively a first busbar feeding device and a second busbar feeding device, and there are two membrane belt feeding devices 4, which are respectively a first membrane belt feeding device and a second membrane belt feeding device. The first busbar feeding device and the first membrane belt feeding device are matched together, and the second busbar feeding device and the second membrane belt feeding device are matched together.

[0185] The first busbar feeding device and the second membrane belt feeding device are both located at one end of the support device 2 along the length direction, and the second busbar feeding device and the first membrane belt feeding device are both located at the other end of the support device 2 along the length direction. The first busbar feeding device, the first membrane belt feeding device, the second busbar feeding device, and the second membrane belt feeding device are arranged diagonally and crosswise.

[0186] exist Figure 8 In the middle, the first busbar feeding device is located on the lower left side of the support device 2, the second membrane belt feeding device is located on the upper left side of the support device 2, the second busbar feeding device is located on the lower right side of the support device 2, and the first membrane belt feeding device is located on the upper right side of the support device 2. Figure 8 As shown, the first busbar feeding device, the first membrane belt feeding device, the second busbar feeding device, and the second membrane belt feeding device are arranged obliquely and crosswise, which can simultaneously complete the feeding of two sets of busbars and membrane belts without interference between the feeding devices, thereby improving processing efficiency.

[0187] Based on the above structure, in order to coordinate the synchronous application of the two sets of busbars and membrane tapes, the number of traction devices 5, busbar cutting devices 6, and membrane tape cutting devices 7 are all two.

[0188] Reference Figure 13 In some embodiments, the busbar feeding device 3 includes a busbar feeding frame 31 and a plurality of busbar roll feeding mechanisms 32 disposed on the busbar feeding frame 31. The busbar lead-out positions of the plurality of busbar roll feeding mechanisms 32 are arranged along a second direction. The busbar feeding frame 31 is configured to be movable relative to the traction device 5 along the second direction.

[0189] And / or, the film tape feeding device 4 includes a film tape feeding frame 41 and a plurality of film tape roll feeding mechanisms 42 disposed on the film tape feeding frame 41, the film tape lead-out positions of the plurality of film tape roll feeding mechanisms 42 being arranged along a second direction, and the film tape feeding frame 41 being configured to be movable relative to the traction device 5 along the second direction.

[0190] By setting up multiple busbar roll feeding mechanisms 32, after the current busbar roll feeding mechanism 32 is exhausted, the busbar feeder 31 can be moved along the second direction to switch to another busbar roll feeding mechanism 32, thereby enabling rapid material replenishment and improving the processing efficiency of the equipment. Similarly, by setting up multiple film roll feeding mechanisms 42, after the current film roll feeding mechanism 42 is exhausted, the film roll feeder 41 can be moved along the second direction to switch to another film roll feeding mechanism 42.

[0191] Figure 13 In the illustrated embodiment, each busbar feeding device 3 includes two busbar roll feeding mechanisms 32, and each membrane belt feeding device 4 includes two membrane belt roll feeding mechanisms 42. During operation, the two feeding mechanisms serve as backups for each other, thereby reducing the time required for material replenishment. Furthermore, in the busbar feeding device 3 and membrane belt feeding device 4 located at the same end of the supporting device 2, the busbar feeding frame 31 and the membrane belt feeding frame 41 are formed into a whole by welding or bolting, thereby realizing simultaneous material replenishment of the busbar and membrane belt.

[0192] The busbars and membrane belts can be fed using either manual or automatic feeding methods. When automatic feeding is used, the bypass busbar prefabrication equipment also includes a material changing device 9. The material changing device 9 includes a material changing drive source 91, which is mounted on the equipment body and configured to drive the busbar feeder 31 and / or the membrane belt feeder 41 to move relative to the traction device 5 in a second direction.

[0193] Figure 13 In the illustrated embodiment, there are two material changing devices 9, each located at one end of the supporting device 2. The power output of each material changing drive source 91 is connected to both the busbar feeder 31 and the membrane belt feeder 41 on the same side. Thus, the material changing drive source 91 can drive the busbar feeder 31 and the membrane belt feeder 41 on the same side to move synchronously. To ensure smoother movement of the busbar feeder 31 and the membrane belt feeder 41, the material changing device 9 includes a material changing slide rail 92 mounted on the equipment body. The busbar feeder 31 and the membrane belt feeder 41 on the same side are simultaneously slidably mounted on the material changing slide rail 92, ensuring that they move along the second direction.

[0194] It should be noted that all drive sources described in this application can be any one of an electric motor, an electric cylinder, or a piston cylinder, and this application does not impose specific restrictions on the type of drive source.

[0195] In summary, the bypass busbar prefabrication equipment provided in this application embodiment can perform traction, correction, cutting, bonding, and hot pressing processes for one, two, or more sets of busbars and membrane strips, without requiring manual intervention, achieving a high degree of automation. In the traction process, a set of busbars and membrane strips are pulled to a specified length using the same traction device 5, saving one traction device 5 and ensuring that the pulled busbars and membrane strips are in the same position. Therefore, only simple lifting and lowering of the cut busbar segment 100 is needed to align and bond it with the membrane strip. For busbars and membrane strips that deviate from the set trajectory during traction, the correction device 8 can correct their deviation, ensuring that the cut busbar segment 100 and membrane strip segment are in the set position. In the cutting process, both the busbars and membrane strips are cut by clamping before cutting, thereby improving cutting accuracy. In the hot pressing process, the busbar segment 100 is heated to fix the busbar segment 100 and the membrane belt through hot pressing, thus avoiding the problem of damage to the membrane belt due to overheating.

[0196] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
